مربع
Also known as 2-orthoplex, bicross, 2-cube, 2-cross-polytope, regular quadrilateral
In geometry, a square is a regular quadrilateral. It has four straight sides of equal length and four equal angles. Squares are special cases of rectangles, which have four equal angles, and of rhombuses, which have four equal sides. As with all rectangles, a square's angles are right angles (90 degrees, or Pi|/2 radians), making adjacent sides perpendicular. The area of a square is the side length multiplied by itself, and so in algebra, multiplying a number by itself is called squaring.
AI overview
A square is a four-sided shape where all sides are equal in length and all corners form right angles (90 degrees). Squares matter because they're fundamental in geometry and mathematics—their properties are used to calculate area, and the concept of "squaring" a number (multiplying it by itself) is named after this shape's mathematical importance.
